moot-surronrrno' ATTACHMENT T0 MOTOR-DRIVEN VEHICLES."

constructed apparatus which may be connected to motor driven vehicles, morepartic- I 'ularly to tractors, of various forms and sizes without material structural change in the apparatus and no change whatever inthe vehicle to which it is attached.

-, Another Object of the invention is to pro vide an apparatusof this character which may be projected for use, or disposed in ele-' vated position when not in' use, or when the tions, and are .pivotallyunitedat '29, Each vehicle is being transported.

With these and-other objects in view, the

invention consists 'in'certain novel features of construction as hereinaftershown and described and then specifically pointed out in the claims, and in the drawings illustrative 'of the preferred embodiment of the invention. 7 I v l Figure 1 is aside elevation, and Figure'2 1s a plan: View, of the lmproved apparatus together with portions of a con 'v'entional tractor to whichthefapparatus'is connected. v

The improved apparatus includes vertical supporting members 10, I bearing"; against opposite s des of some 'convem'ent portion of "a tractor, for instance 'the radiator indicated at 11, and coupledvin position by'a plurality 'of clamprods 12, and clamp units 13. Y

' 'Attached to the-supporting {members 10 'at the-bottom are'clip devices 14,L'having depending open hooks 14,"and swinging'on each ofthese hooks by' a strap 15 isfa bar 15". The bars15 are connected, together at their outer ends by a transversesupport16. The straps 15 are provided with studs which are indicated at 15 andengage'in'thehooks 14;. The studs 15 are held inposition'by stop bolts 15 r 1 I Rigidly connected by bolts 17 to eachofthe bars 15 is a depending hangermember 'l8, and pivoted at 19 to the lower end of each of the members '18 is an upstanding and'for- Wardly inolined'supporting members 20. At

their upper ends the members '20" are con nected to a table member 21', having the inner portion thereof connected to the sup- Y porting members 20'by verticali braces, one

of which is shown at 2 v Attached to the upper face of the table 21 are L bars 21 which operate to hold the work 7 upon the table.

Means are preferably'provided,' such as chains or the like, one of which is shown at '23, to limit the outward movementof the table, while leaving it freeto swing inwardly toward the member 16,;the object to be herev inafter explained. Aipush spring 23" 'may t- 'alsobeemployed. ""Attached by bolts 24 or'the like,to the outer faces of the supports10 are straps 25,

and pivoted at 26 to one end of each 'strap is an inner brace 27, and pivoted atoneend at 28 to the support '16, are like braces 29. 'The'braces' overlap atjconfronting' porof thebraces 27 is providedwitli a lateral slot, one of which is shown at 30,' afnd each of the braces 29 isprovided with a headed stud 31 to enter the slot when the braces vare disposed in longitudinal alinement. By this 'meansvthe braces hold thebars 15 and the hanger member 18, and the supporting table 21 in projected position as shown, andare foldable on the pivots 29 to'permitthe device toswing on the hooksil l, whenit is' to be disposed in inoperative position. '7 I ports 10 in position, tierods '32 are employed; and'eaoh coupled at one end at, 33 to the straps 25 {and connected, at the other ends. 31:34 tothe clamp member 35- by which fthetank36 of the tractor is supported;

1 Any required tool'element may be mounted on the support 'l6, but for the'p'urpose. of illustration, a conventional sawf device is shown comprising a shaft 37 mounted in bearings 38 on the member: 16 andcarrying a saw 39, anda'belt pulley 40; Any suitable portion of th'e rotative elements ,of' theotractor may' beYutili'zed to transmit motion to the shaft37 and the tool carried thereby, but

the tractor j'selected for illustration is pro- 05 As a further means "of holding the 49 to receive the saw 39, and the bars 21' nearest the opposite sides of the path of 'the saw are coupled by a transverse head portion 50.

Under some circumstances the tie rods 32 may be located as shown by dotted lines 51, in Fig. 1. V

The improved device is simple in construction and can be made of any suitable material.

Preferably the members 101516 and 21 will be of wood, but all parts maybe of metal, if required.

The preferred embodiment of the invention is disclosed in the drawings and set forth in the specifications but it will be understood that modifications within the scope of the claimed invention may be made in the construction without departing from the principle of the invention or sacrificing any of its advantages.

Having thus described my invention what I claim as new is:
